Is the phasor a time-domain or frequency-domain quantiy?
It is a frequency-domain quantity. In Basic Engineering Circuit Analysis by Irwin, the time domain is written as A*cos(wt+/-THETA) and the frequency domain is written as A*phasor(+/-THETA).A series of phasor measurements, taken at regular intervals over time, can sometimes be useful when studying systems subject to variations in frequency. The electric power system is one example. The power grid nominally operates at 50Hz (or 60Hz), but the actual frequency is constantly changing around this nominal operating point. In this application, each individual phasor measurement represents a frequency domain quantity but a time series of phasor measurements is analyzed using time-domain techniques.

Is impedance triangle a phasor diagram?
Most definitely not, as resistance, reactance, and impedance are not themselves phasor quantities. However, it is derived from a phasor diagram (by dividing a voltage phasor diagram by the reference phasor, current).
When did Phasor Zap happen?
Phasor Zap happened in 1978.
When was Phasor Zap created?
Phasor Zap was created in 1978.
How will be phasor diagram if XL equals XC?
When the inductive reactance (XL) equals the capacitive reactance (XC) in an AC circuit, the circuit is said to be in resonance. In a phasor diagram, the voltage phasor across the inductor (V_L) and the voltage phasor across the capacitor (V_C) will be equal in magnitude but opposite in direction, effectively canceling each other out. As a result, the total voltage phasor will be aligned with the current phasor, indicating that the circuit behaves as purely resistive at this point. The current phasor will lead the voltage phasor by 90 degrees in an inductive circuit and lag in a capacitive circuit, but at resonance, they are in phase.
What is mean by dynamic phasor?
Phasor diagram is graphical representation of various electrical parameters in terms of their magnitude and angle.
Why do you use phasor Diagram?
phasor diagram is nothing but the vectorial representation of time-varying periodic signals(most common are sine and cosine) , whose magnitude is given by the amplitude of the signal and the direction (angle..) is given by the phase difference. this makes life a lot easier , calculations in vector-algebra domain is more easier when compared to trigonometric domain because here we can resolve any 'n' no. of vectors and by performing simple algebra of addition and subtraction gives us the desired result. Whereas in trigonometric domain we need to expansions like sin(A+B),cos(A-B) etc etc which is a laborious task
What is a phasor diagram and why you draw it?
Theoretically, it can be drawn at any angle. Normally, however. it is drawn along the real, positive, axis (i.e. facing East). For series circuits, the reference phasor is the current and, for parallel circuits, the reference phasor is the voltage. For transformers, it is the flux.
What is the difference between vector and phaser diagram?
A(t) = Am sin(ωt ± Φ) representing the sinusoid in the time-domain form. But when presented mathematically in this way it is sometimes difficult to visualise this angular or phase difference between two or more sinusoidal waveforms so sinusoids can also be represented graphically in the spacial or phasor-domain form by aPhasor Diagram, and this is achieved by using the rotating vector method.Ansh
Explain the Phaser diagram of inductive load?

How do you add and subtract two sinusoidal ac waveforms graphically and by phasor diagram?
I already have the graph drawn on graph paper with 2 waves on , my phase shift is 1.5 and 180degrees. Anyone know how to add and subtract the sinusoidal ac waveforms on the graph, and by phasor diagram?
What is the input signal of key phasor?
The input signal of a key phasor is typically a periodic waveform, such as a sinusoidal signal, used to establish a reference for measuring and analyzing the phase relationship between different signals in power systems. It serves as a synchronization point for phasor measurement units (PMUs) to accurately capture the magnitude and phase of electrical quantities like voltage and current. This reference signal is crucial for applications in monitoring, control, and protection of electrical grids.
